The ?-decay chain 109Xe ? 105Te ? 101Sn was identified at the Holifield Radioactive Ion Beam Facility. Advances in digital electronics have made possible the identification of both alpha emitters in the same experiment despite the disparate half-lives of 13 ?2?ms and 620 ?70?ns for 109Xe and 105Te, respectively. Two ?-decay transitions were observed from 109Xe with Q?values of 4067 ?10 and 4217 ?8?keV. One transition between the ground states of 105Te and 101Sn was observed with a Q?value of 4889 ?6?keV. Using the measured half-lives, branching ratios, and Q?values the reduced ?-decay widths, ?2, were determined. Comparison of the ?2value for 105Te with 213Po indicates a ?superallowed" character in the ? emission of 105Te. |
